Thermodynamics and spin mapping of quantum excitations in a Heisenberg spin heptamer
A. Roxburgh, J. T. Haraldsen
In this study, we examine the thermodynamics and spin dynamics of spin-1/2 and spin-3/2 heptamers. Through an exact diagonalization of the isotropic Heisenberg Hamiltonian, we find…
A Functional Taxonomy of Music Generation Systems
Dorien Herremans, Ching-Hua Chuan, Elaine Chew
Digital advances have transformed the face of automatic music generation since its beginnings at the dawn of computing. Despite the many breakthroughs, issues such as the musical t…
Spin channel induced directional dependent spin exchange interactions between divacantly substituted Fe atoms in graphene
R. Putnam, A. V. Balatsky, J. T. Haraldsen
In this study, we investigate the isolated magnetic interactions between two identical Fe atoms divacantly-substituted into graphene. Using density functional theory, we simulated…
A Balancing Domain Decomposition by Constraints Preconditioner for a Interior Penalty Method
Susanne C. Brenner, Eun-Hee Park, Li-Yeng Sung +1
We develop a nonoverlapping domain decomposition preconditioner for the interior penalty method, a discontinuous Galerkin method, for the biharmonic problem. The precondition…
Superconducting nanowire single-photon detector with integrated impedance-matching taper
Di Zhu, Marco Colangelo, Boris A. Korzh +11
Conventional readout of a superconducting nanowire single-photon detector (SNSPD) sets an upper bound on the output voltage to be the product of the bias current and the load imped…
The Eternal Game Chromatic Number of a Graph
William Klostermeyer, Hannah Mendoza
Game coloring is a well-studied two-player game in which each player properly colors one vertex of a graph at a time until all the vertices are colored. An `eternal' version of gam…
Jitter Characterization of a Dual-Readout SNSPD
D. F. Santavicca, B. Noble, C. Kilgore +4
To better understand the origins of the timing resolution, also known as jitter, of superconducting nanowire single-photon detectors (SNSPDs), we have performed timing characteriza…
Latent Gaussian Count Time Series
Yisu Jia, Stefanos Kechagias, James Livsey +2
This paper develops the theory and methods for modeling a stationary count time series via Gaussian transformations. The techniques use a latent Gaussian process and a distribution…
Linear and nonlinear optical probe of the ferroelectric-like phase transition in a polar metal, LiOsO3
Haricharan Padmanabhan, Yoonsang Park, Danilo Puggioni +7
LiOsO3 is one of the first materials identified in a recent literature as a 'polar metal', a class of materials that are simultaneously noncentrosymmetric and metallic. In this wor…
Grassmann graphs, degenerate DAHA, and non-symmetric dual -Hahn polynomials
Jae-Ho Lee
We discuss the Grassmann graph with , having as vertices the -dimensional subspaces of an -dimensional vector space over the finite field …
VERITAS and Fermi-LAT observations of new HAWC sources
VERITAS Collaboration, A. U. Abeysekara, A. Archer +280
The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…
Spatial dependence of the superexchange interactions for transition-metal trimers in graphene
Charles B. Crook, Gregory Houchins, Jian-Xin Zhu +3
This study examines the magnetic interactions between spatially-variable manganese and chromium trimers substituted into a graphene superlattice. Using density functional theory, w…
Correlation Clustering Based Coalition Formation For Multi-Robot Task Allocation
Ayan Dutta, Vladimir Ufimtsev, Asai Asaithambi
In this paper, we study the multi-robot task allocation problem where a group of robots needs to be allocated to a set of tasks so that the tasks can be finished optimally. One tas…
Inequalities and separation for covariant Schrödinger operators
Ognjen Milatovic, Hemanth Saratchandran
We consider a differential expression , where is a metric covariant derivative on a Hermitian bundle over a geodesically compl…
A distributed electrical model for superconducting nanowire single photon detectors
Qing-Yuan Zhao, Daniel F. Santavicca, Di Zhu +2
To analyze the switching dynamics and output performance of a superconducting nanowire single photon detector (SNSPD), the nanowire is usually modelled as an inductor in series wit…
Search for Spatial Extension in High-Latitude Sources Detected by the Fermi Large Area Telescope
LAT Collaboration, Jonathan Biteau
We present a search for spatial extension in high-latitude () sources in recent Fermi point source catalogs. The result is the Fermi High-Latitude Extended Sources Cat…
Dark Matter implications of DAMA/LIBRA-phase2 results
Sebastian Baum, Katherine Freese, Chris Kelso
Recently, the DAMA/LIBRA collaboration released updated results from their search for the annual modulation signal from Dark Matter (DM) scattering in the detector. Besides approxi…
Einstein@Home discovers a radio-quiet gamma-ray millisecond pulsar
C. J. Clark, H. J. Pletsch, J. Wu +18
Millisecond pulsars (MSPs) are old neutron stars that spin hundreds of times per second and appear to pulsate as their emission beams cross our line of sight. To date, radio pulsat…
Manifolds of magnetic ordered states and excitations in the almost Heisenberg pyrochlore antiferromagnet MgCr2O4
S. Gao, K. Guratinder, V. Tsurkan +18
In spinels ACr2O4 (A=Mg, Zn) realisation of the classical pyrochlore Heisenberg antiferromagnet model is complicated by a strong spin-lattice coupling: the extensive degeneracy of…
A Deep X-ray View of the Synchrotron-Dominated Supernova Remnant G330.2+1.0
Brian J. Williams, John W. Hewitt, Robert Petre +1
We present moderately deep (125 ks) {\it XMM-Newton} observations of supernova remnant G330.21.0. This remnant is one of only a few known that fall into "synchrotron-dominated"…
